ONGC Completes Drilling of Second Geothermal Well in Ladakh.

State-owned Oil and Natural Gas Corporation (ONGC) has completed drilling its second geothermal well in Ladakh's Puga Valley, marking another milestone in the development of India's first pilot geothermal power plant.

The well, drilled by ONGC Energy Centre, the company's research and development arm, reached a depth of 1,000 metres at an altitude of over 14,000 feet in about a month, improving on both the timeline and cost of the company's first geothermal drilling campaign, ONGC said in a post on social media.

The second well follows the successful drilling of ONGC's first geothermal well in the Puga Valley, which produced steam at temperatures exceeding the boiling point of water, demonstrating the region's significant geothermal energy potential.

The project is part of ONGC's efforts to harness geothermal resources in Ladakh and advance the development of India's first pilot geothermal power generation facility.
